Found this roll hunting and it's left me scratching my head. The pennies are there for color reference even though they are really dark themselves so I'm assuming toning plays a part on those two... But that quarter though...any thoughts? I'm afraid to scratch it because it is in decent shape as it is. It has a couple chips missing from the front around the date on the obverse and a chip above the "s" in states on the reverse. All chips reveal that reddish-brown color. I apologize for the pic sizes but my crop isn't working on my phone.
